The occupancy detection device, with the use of at least one sensor, at least one additional status is communicated to at least one mobile device. A plurality of occupancy detectors can be connected in a mesh or a star network and communicate to at least one mobile device by a wireless communication method or combinations of a wired and a wireless communication methods.

FIELD OF THE INVENTION

The present invention relates to an occupancy detection, and more particularly it relates to an occupancy detection device, and related system and method, that detect occupancy at and near a table or in a swimming pool or in some type of a platform by using at least one of the numerous sensor options, detects presence of at least one person and a moving object and an operating object, and indicates the status of the table or the swimming pool with at least one light source and on at least one mobile device via a wireless and/or wired combinations of communication means.

BACKGROUND OF THE INVENTION

In a restaurant, a meeting hall or a dinning setting there are multiple tables and some of them are occupied by people and some of them are not. There is a need for people attending to a gathering to know, which tables are occupied, which tables are not occupied, and the busyness of the gathering in a convenient way. For instance, if a restaurant is a buffet style, one could leave the table and when he/she return to the table and realize it has been cleaned up or taken over by a new occupant. Similarly, in a swimming pool, it is desirable to monitor the activity in the pool in case of intrusion, when the homeowner is away. In other case such as children's safety in the swimming pool, it is desirable to monitor children's activity when adults are not nearby the pool. Likewise, it is beneficial in a commercial swimming pool to monitor the presence of hotel customers in the pool.

The conventional occupancy detectors do not apparently describe about nor are they specifically tailored toward detecting occupancy at and near the table of at least one person. The conventional occupancy detectors also do not disclose about indication of the status of the table and user inputs in variety of ways. Further, the conventional occupancy detectors do not teach anything about monitoring the activities in the private or commercial swimming pool or monitoring the presence of at least one person in and near the swimming pool. They are clearly differentiable from the present invention both in utility and design. The unique characteristics and features of the device of the present invention are therefore, unrepresented within the prior arts. Further, the conventional occupancy detectors encounter various problems along with functional limitations. Hence, there is a significant need and void in the market for inventing an occupancy detection device which detect occupancy at and near a table of at least one person. Further, there is a need for inventing an occupancy detection device which monitor the activities in the private or commercial swimming pool and/or monitor the presence of at least one person in and near the swimming pool.

SUMMARY OF THE INVENTION

The present invention relates to an occupancy detection device, and related system and method, which address the needs which were not fulfilled by the conventional arts. According to an embodiment of the present invention, a system and a method is provided to detect occupancy at and near a table of at least one person. The present invention is able to use a light source to indicate the status of the table and accept user inputs in variety of ways, wherein the status are in form of, but not limited to messages such as “occupied”, “unoccupied”, “reserved”, “out of service”, “happy birthday”. The status also include measurements, calculations, estimations and any inputs and compilations of inputs from its components of the device. The occupancy detection device is able to stand by itself and it is able stand with a connection to at least one mobile device by means of wireless and/or wired means of communication. The occupancy detection device is also configured to be a member of a network, wherein a plurality of occupancy detection devices are on other tables connected in a wireless network. Each occupancy detection device is able to communicate its status to and receive commands from a remote device wirelessly. The remote device can be a central device or a mobile device.

According to an embodiment of the present invention, a system and a method is provided to detect swimming pool occupancy of at least one person in the pool and the occupancy of at least one running object, and communicate this status to a remote device wirelessly and/or wired means of communication. The present invention is able to detect, measure, calculate and estimate various aspects of the pool status and pool system, but not limited to, the status as “rainy weather”, “windy weather”, “pump is running”, “pump is stopped”, “water depth” and “water amount in the pool”.

According to an embodiment of the present invention, the occupancy detection device detects the presence of an occupant, comprising at least one accelerometer, a microphone, a vibration sensor, a laser, a liDAR, a motion detector, an ultrasound sensor, a time of flight sensor and with a sensor similar in nature of detection. The occupancy detection device then indicates through a light source on the table for people to see the status of the table. A built-in time delay handles the situations when the occupants leave the table temporarily for instance to get more food or any other reason, the light source indicator stays on indicating occupied table status.

Furthermore, the occupancy detection device of the present invention comprises a wireless communication capability to inform the staff about the status of the tables and track the turn-over of the occupants. Furthermore, for example, in a resort hotel setting, the status of tables is communicated to a mobile app on a mobile device for hotel guests to adjust their time of arrival to the restaurant depending on the busyness.

Furthermore, the occupancy detection device of the present invention comprises a service button for the restaurant workers to clean the dirty dishes off the table without changing the occupied status or to take care of any other need the guests might have. The occupancy detection device comprises a second user input button that bypasses the sensor detecting the occupancy and eliminating the sensor needed for detection to change the status of the table to occupied status. With the press of the second user input button, the occupancy status of the device is initiated with a timeout timer, which can be adjustable. The occupancy detection device comprises a third button that is used to clear the occupancy indication of the table manually. In this embodiment, button concept is used for a purpose to achieve simplicity to explain the user input capabilities of the present invention. However, the buttons mentioned here are not limited to physical buttons. It is a collection of the user inputs to activate certain functionality. Therefore, the user inputs can be implemented in variety of ways and combinations such as a dial and buttons with a display, or a display with just buttons or a display with capacitive touch buttons or a gesture detection sensor or a Near Field Communication (NFC) or a Bluetooth connection.

According to another embodiment of the present invention, the occupancy detection device can be used in a swimming pool as a pool occupancy detector. Detecting presence of at least one person in a swimming pool has various benefits. One of them is monitoring the activity in the pool in case of intrusion, when the homeowner is away. Another one is monitoring children's activity when adults are not nearby the pool. Similarly, it is beneficial in a commercial pool application to monitor the presence of hotel customers in the pool.

Some swimming pool pumping systems has an SVRS (safety vacuum release system) feature. SVRS in the swimming pool when implemented as part of a pump motor control system is used to detect the presence of an entrapment of a person and to shut off the pump to save the life of that person. According to another embodiment, the present invention can be used in a swimming pool application to transmit the occupancy status to a pool pump controller or a pool automation system and not allow the pumping system to get into a non-safe SVRS (safety vacuum release system) operation while a swimmer is present in the pool. According to another embodiment, the pool pump control system can transmit to the pool occupancy detector the state of the SVRS operation, wherein the pool occupancy detector can warn the people not to enter the pool for certain amount of time. This warning can be in the way of flashing light or warning sound or signal transmitted to a mobile device. The pool occupancy detector can also embody rain and wind detection, sunlight load detection. This information can be transmitted to the user via wireless communication means.

The occupancy status of the swimming pool can be utilized by the automation system to keep the pool cleaner. When a person or persons are detected in the pool, the automation system or the pool pump controller uses this information to increase the pump speed to increase the water circulation and filtering water more often. Aforesaid feature will change the regular run schedule of the pool pump until the swimmers are clear from the pool for a certain amount of time, wherein the automation system or the pool pump controller will allow the speed of the pump to return to normal schedule. According to another embodiment, the status information can be used along with a chemical treatment device information to decide when to modify the pump running speed depending on the chemical composition. The same status information can be used by the chemical treatment device to change the treatment schedule and adjust the amount of chemicals used. In addition, the pool occupancy detector device can detect moving and operating objects such as pool cleaners in the pool. Similarly, a special pool pump speed is run to fit the need of the cleaner by making the pump run schedule adaptive based on the need of swimmers and the pool.

The present invention can be arranged in multiple power supply options such as solar cell charged battery, solar cell charged battery with super capacitor, solar charged super capacitor, rechargeable battery from an outlet source or just with a non-rechargeable battery power source.

Other aspects of the present invention will be clearer after reading the following detailed description of the preferred embodiment with reference to the accompanying and drawings and viewed in accordance with the appended claims.
